I didn't know who to reach out to and when I googled support for the Sister of the Groom this website with its forums, popped up. So here is my dilemma, my brother is getting married to a wonderful girl in about 60 days. Its a big ceremony and it should be lovely. My future sister-in-law (FSIL) comes from one of the the largest families I have ever known, which seems great. However, almost all of my extended family has past away, about 10 or 20 years ago so the big family thing is totally new to me. My whole life all I have had is my brother and parents. So now that these in-laws are in our life my brother has a lot of family requirements or engagements that I am not invited to; and honestly that is probably normal. But the overwelhming feeling of being left out and alone is killing me. I really really really just miss my brother and my family. And with all this wedding planning stuff coming up it is obviously not a great time to bring up the fact that my FSIL and her family have taken my brother from me, but it is truly how it feels and I am so hurt and sad at this point I don't think I can make it through the wedding day without sobbing because I am just so upset.

To give you a bit more back story, I hosted a Thanksgiving dinner that my brother and FSIL ended up not being able to attend because all of the Thanksgiving festivities with her family ran late. At Christmas my brother and FSIL, came to my parents house with me to have coffee and a piece of coffee cake but then took their gifts to her parent's house. At Easter when my brother told me he would be with his in-laws and not me, I lost it and basically accused him of taking her last name (not my proudest moment) so last minute my brother showed up at Easter for me but without my FSIL. When I had to put my dog down, my brother wouldn't answer the phone because he was with his in-laws but when he heard my dog had died, only he showed up later.

He was/is my best friend and I am loosing him, he doesn't want me as his best friend anymore he wants my FSIL. How can I even begin to cope with that?

Please Please Please any helpful advise I can get from someone with another perspective is priceless.
